I am having trouble with the filler cap on the cam cover leaking.
i have not yet found the correct three eared cap and so far I have avoided buying the reproduction one.
This cheapo `tin pot` cap has worked very well for ten years but is now leaking.
I have cut a few seals out of various materials but with only short term success.
Can you suggest a source for the correct seal or suggest what material to make one from.
The search facility on this forum is still not working.
I have checked ebay and the local car parts shop and I have oil deflector plate over the No4 cam.
Any advice will be welcome

Eric, I bought replacement seals from QED (part # 103029) https://qedmotorsport.co.uk/product/oil-filler-cap-seal/ but that did not completely solve the issue.
Strange, that did solve the issue for me...
Not my original idea, copied from John Clegg & others...
Feel free to copy the design...

I have gone to silicone on my NA and boosted vehicles.
$2 or £1 because they dont distort like rubber.

Find out where the limits are, and start from there

Off piste: How long does it take to fill the sump with an oil deftector like that fitted? It's bad enough without.

Thankyou Phil, That`s fixed it.
I bought two of the seals you suggested and had to fit both to obtain a satisfactory fit. I assume that was because the cap is rubbish from China. Another leak stopped. OK for now.
